sciatic nerve‚ speed of transmission and degree of myelination can all have an effect on the sciatic nerve and therefore the peak contractile force of B. Marinus. The diameter of the axon in the sciatic nerve would impact how fast the action potential is conceived down the axon to the synaptic cleft and muscle (Firmin‚ L. 2014). If one of the toads had a smaller axon diameter it would allow for resistance to movement to occur due to friction. The diameter of the axon in the sciatic nerve would therefore
